\part{PNG Compression}
I use the following two tools:

\begin{itemize}
\item{AdvanceCOMP 1\footnote{http://advancemame.sourceforge.net/comp-readme.html}}
\item{OptiPNG 2\footnote{http://optipng.sourceforge.net/}}
\end{itemize}
I run the following code in each graphics directory:

\begin{verbatim}

advpng -z4 *.png
optipng -o7 *.png
\end{verbatim}

See \texttt{horde/framework/devtools/horde-compress-pngs.php} 3\footnote{http://cvs.horde.org/framework/devtools/horde-compress-pngs.php}.
